IMPROVEMENT IN STEAM-FLOWS.

Specification forming part of Letters Patent No. 26,279, `dated November 29,'

To all whom 'it may concern:

Beit known that we, A.E. MCGAUGHEY and S. N. MCGAUGHEY, of Wastedo, in the county of Goodhue and State of Minnesota, have invented a new and Improved Steam-Plow; and

we do hereby declare that the following is a full, clear, and exact description of the same,

reference being had to the annexed drawings, making apart of this specification, in which- Figure 1 is a side sectional view of our invention, taken iu the line a' w, Fig. 3. Fig. 2 is a back View of the same. Fig. 3 is a horizontal section ofthe same, taken in the line x w', Fig. 1.

Similar letters of reference indicate corre` sponding parts in the Iseveral figures.

This invention consists in-the employment or use of a series of intermittingly rotating and oscillating plows and 'oscillating or vibrating harrows so arranged as to operate in a transverse direction with the movement of the machine, substantially as hereinafter described, whereby several advantages are obtained over all previous arrangements of plows that have passed under our observation.

To enable those skilled in the art to fully understand and construct our invention, we will proceed to describe it. f

A represents the frame of the machine,which may be of wood and constructed in any proper way to support the working parts. The front end of the frame A is supported by a casterwbeel, 4B, and the back partis supported by wheels C G, one at each side of the frame.

D is a boiler, of cylindrical form,which is suspended in the frame Afrom a hollow shaft, E, by means of bars a.. The boiler D is so balanced as to have atendency to remain in a horizontal position, the shaft E being fitted loosely in its bearings b`.

F is a tube which communicates with the hol low shaft E and with the lower part ofthe boiler D, and Gr is a tube which also communicates with said tube and the upper part of the boiler.

A stop is placed in the shaft E, between the two tubes F G, and wateris forced into one end of shaft E and through the tube F into the boiler to supply the same, steam passing through the ing a crank, e, on eachA end, the two cranks being placed in reverse poitions and connected by rods ff to levers 0 O, which are placed one at each side of the frame A, and have each a connecting-rod, P, attached toits lower end, the back ends of said rods being connected to arms P P,which are attached to vertical shafts Q Q in a sash, It, a` shaft, Q, being near each.

end of said sash It. The sash Ris simplya frame fitted betweennprigbts g g atthe back part of frame A, and allowed to slide up and down between the uprights, thesash being adjusted by a .screw-rod, It, asshown clearlyin Fig. 2. The lower endsof theshafts Q Q pass through bars i, the latter beingsecured to the shafts. The bars i extend across the lower beam of the sash R, and their front ends are each connected by rodsj to similar bars,"i'A if, which are placed ou shafts QQ in the sash R.' The back parts of the bars ii extend downward and form the back bcaringsfor shaftsk, the front ends of which pass through the front parts of the bars i i', which also extend downward and form bearings for the front parts of the shaft, as shown clearly in Fig. 1.

On the frontend of each shaft 1c a hub, l, is placed. To these hubs l three radial arms, m, are attached, and to the end of each arm a plow, S, is secured.y These plows are of the usual form, such as are used for turning the sod or earth, each plow being provided with a mold-board and landside. '.lhe inner side of each hub l is notched, so as to form ratchettooth projections, as shown clearly in Fig.` 3.

0n the back part of each shaft 7c a pinion, u,

pinions n are notched similarto the back sides` of the hubs l, so as to form ratchet-tooth projections. The teeth of the pinions 'n have a reverse position to those of the hubs l, as shown clearly in Fig. 1.

On each shaft k a spiral spring, p, is placed, each springbeingbetween two slides, q'q, placed on its shaft k, which slides have rods 1' s attached, the rods s passing through the hubs o and bearing against the faces or toothed sides of the pinions n, and the rods r passing through the front vertical portions of the bars i i and bearin g against the toothed faces of the hubs l. (See Fig. 1.)

ax, on it, that gears into a toothed wheel, b", at-

tached to and concentric with one of the wheels C. If necessary or desirable, both wheels G C may be thus connected with the shaft N.

The operation of the machine is as follows: The machine is propelled, it will be seen, by the application of power from the cylinders H, through' the medium of the connecting-rods K, cranks c, gearing d M, belt u, and gearing a* b". As the machine moves along, the bars z' i', and consequently the shafts k and ploWsjS, oscillate or move in the arcs of circles and transversely with the plane of the movement of the machine. This movement ofthe shafts k is produced by the cranks e, levers O O, connecting-rods P, arms P', shafts Q Q', andthe bars fi t', connected by the rodsj.

Besides this movement of the plows S another one is given them by the pinions n and rack T. This latter movement, which is a rotating one, permits of the return motion of the plows after forming the furrow during their direct movement. The plows of two of the shafts 7c turn a furrow while moving from right to left, and the other two While moving in an opposite direction. When the plows S are at Work, or during the movement in which the furrows are formed, the plows are ,retained in proper position by the rods r, against which the teeth on the hubsl catch; and during the return or opposite movement of the shafts 7c the plows rotate out of the ground-that is to say, the ones that made the previous furrowsand the succeeding plow is brought in proper position for work, this latter movement being produced by the pinions u and racks T, the rods s catching into the pinions n and connecting the latter with the shafts k. The plows are made to passa greater or less depth into the earth by adjusting the sash R.

To the back end of each bar i t" an arm, U, is attached. These arms are provided with rakes or harrows V, as shown clearly in Fig. 1 It will be seen that they have the same movement as the plows, and consequently smooth and level the work performedby them.

The boiler, in consequence of bein g suspended in the frame as sho-wn, retains itself in a horizontal position by its own' gravity.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. The plows S, attached to radial arms m or oscillating shafts k, and arranged with the pinions n, rack T, ratchet-toothed hubsl, and stop-rods 1' s, to operate substantially as and forthe purpose set forth.

' 2. In connection with the plows S, arranged and operated as described, the rakes or harrows V, attached to the bars t' t', for the purpose specified.
